Iiflange ziyinxalenye ebalulekileyo kwiinkqubo zombhobho, esetyenziselwa ukudibanisa imibhobho, iivalve, iimpompo, kunye nezinye izixhobo. Xa ukhetha iiflange, imigangatho emibini ephambili kufuneka ithathelwe ingqalelo – DN (Dimension Nominal) kunye ne-ANSI (Iziko leMigangatho yeSizwe yaseMelika). Nangona zombini ziqhelekileyo, kukho umahluko ongundoqo onokuwuqonda xa ukhetha phakathi kwe-DN vs ANSI flanges. Eli nqaku liza kuthelekisa i-dn vs ansi flanges ngokweenkcukacha ukukunceda wenze ukhetho olufanelekileyo.
Intshayelelo
Iiflange zibonelela ngendlela yokudibanisa imibhobho kunye nokuhambisa ulwelo okanye iigesi ngokubopha kunye neegaskets phakathi kwazo ukutywina umdibaniso.. Zisetyenziswa kwizicelo ezininzi ezivela kwishishini leoli kunye negesi ukuya ekutyeni nasekulungiseni isiselo, izixhobo zombane, kunye nokuninzi.
Kukho imigangatho emibini ephambili yezizwe ngezizwe yobukhulu beflange kunye neereyithingi:
- DN – I-Dimensional Nominal (Umgangatho waseYurophu/ISO)
- ANSI – Iziko leMigangatho yeSizwe yaseMelika (Umgangatho waseMelika)
Ngelixa bobabini balandela umgaqo ofanayo woyilo, kukho iyantlukwano kwimilinganiselo, imilinganiselo yoxinzelelo, ubuso, kunye neepateni zebholithi ezenza ukuba zingatshintshi. Ukuqonda i-dn vs ansi flanges kuya kuqinisekisa ukuba ukhetha iiflange ezifanelekileyo kwinkqubo yakho yokubhobhoza.
Iiyantlukwano eziphambili phakathi kwe-DN kunye ne-ANSI Flanges
Xa uvavanya i-dn vs ansi flanges, ezi zilandelayo zizinto eziphambili zokuthelekisa:
Imilinganiselo
- Iiflange ze-DN zisekelwe kubungakanani bombhobho oqhelekileyo kunye nokwandiswa kwedayamitha eqhelekileyo.
- Iiflange ze-ANSI zinemilinganiselo ye-intshi eqhelekileyo engahambelani ngokuthe ngqo nobungakanani bombhobho.
Oku kuthetha ukuba i-DN 100 i-flange ihambelana nombhobho we-100mm, ngelixa i-ANSI 4 "flange ine-bore of approx. 4.5”. Iiflange ze-DN zisebenzisa i-metrics ngelixa i-ANSI isebenzisa iiyunithi zobukhosi.
Amanqaku oxinzelelo
- Iiflange ze-DN zisebenzisa ukulinganisa kwe-PN – uxinzelelo oluphezulu kwi-BAR kwiqondo lokushisa elinikeziweyo.
- Iiflange ze-ANSI zisebenzisa i-Class rating – uxinzelelo lwe-psi oluphezulu olusekelwe kumandla wezinto eziphathekayo.
Umzekelo, iDN150 PN16 iflange = ANSI 6” 150# flange kwisakhono sokuphatha uxinzelelo.
Izimbo zokujongana
- Iiflange ze-DN zisebenzisa iFomu B1 okanye iB2 ezijongene nazo.
- Iiflange ze-ANSI zisebenzisa ubuso obuphakanyisiweyo (RF) okanye Ubuso obuFcaba (FF) ubuso.
I-B1 iyafana neRF, ngelixa i-B2 ithelekiseka ne-FF. Ubuso kufuneka buhambelane nokutywinwa okufanelekileyo.
Izangqa zeBolt
- Imingxuma yebholithi ye-DN ibekwe ngokusekwe kwidayamitha yegama.
- Izangqa zebholithi ze-ANSI zisekwe kwi-flange class rating.
Imingxuma yebholiti ayiyi kulungelelanisa phakathi kwezi ndlela zimbini.
Izinto eziphathekayo
- Iiflange ze-DN zisebenzisa izixhobo ezisekelwe kwimetric – P250GH, 1.4408, njl.
- I-ANSI isebenzisa amabakala asebukhosini/aseMelika – A105, I-A182 F316L, njl.
Izinto eziphathekayo kufuneka zilingane nokusingatha amaqondo obushushu afunekayo kunye noxinzelelo.
Njengokuba ubona, dn vs ansi flanges zineyantlukwano ezimbalwa ezenza zingatshintsheki. Ukudibanisa ezi zimbini kudla ngokukhokelela ekuvuzeni, umonakalo, kunye neminye imiba.
